consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For example, CPU speed,
Advantech products used, other hardware and software used, etc.) Note anything
abnormal and list any onscreen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your manual, product, and any
helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandize
authorization) number from your dealer. This allows us to process your return more
quickly.
4. Carefully pack the defective product, a fully-completed Repair and Replacement Order
Card and a photocopy proof of purchase date (such as your sales receipt) in a shippable

Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from damage.
1. To avoid electrical shock, always disconnect the power from your PC chassis before you
work on it. Don't touch any components on the CPU card or other cards while the PC is
on.
2. Disconnect power before making any configuration changes. The sudden rush of power
as you connect a jumper or install a card may damage sensitive electronic components.

Chapter 1 Overview
1.1 Introduction
The EKI-2525/2525I/2528/2528I is a cost-effective solution and meets the high
reliability requirements demanded by industrial applications.
1.1.1 High-Speed Transmissions
The EKI-2525/2528 includes a switch controller that can automatically sense
transmission speeds (10/100 Mbps). The RJ-45 interface can also be auto-detected,
so MDI or MDI-X is automatically selected and a crossover cable is not required. All
Ethernet ports have memory buffers that support the store-and-forward mechanism.
This assures that data is properly transmitted.
1.1.2 Dual Power Input
EKI-2525/2525I/2528/2528I redundant power input design is with power reserve
protection to prevent the switch device broken by wrong power wiring. When one of
power input is fail, P-Fail LED will turn on and send an alarm through a relay output for
notifying user.
1.1.3 Flexible Mounting
EKI-2525/2525I/2528/2528I is extremely compact (37 x 140 x 95 mm) and can be
mounted on a DIN-rail or a panel, so it is suitable for any space-constrained
environment.
1.1.4 Advanced Protection
EKI-2525/2525I/2528/2528I supports up to 3,000 VDC surge protection for power line,
and also supports 4000V ESD for Ethernet ports. With these 2 strong protections, it
can secure equipment against unregulated voltage and make systems safer and more
reliable. Further, EKI-2525/2525I/2528/2528I provides currency overload protection
with a resettable fuse to ensure that the device component won’t be damaged by
overload current.
1.1.5 Wide Operating Temperature
The operating temperature of the EKI-2525/2528 is between -10 ~ 60 ℃and the EKI-
2525I/2528I is between -40 ~ 75 ℃. With such a wide range, you can use the EKI-
2525/2525I/2528/2528I in some of the harshest industrial environments that exist.
1.1.6 Easy Troubleshooting
LED indicators make troubleshooting quick and easy. Each 10/100 Base-TX port has 2
LEDs that display the link status, transmission speed and collision status. Also the
three power indicators P1, P2 and P-Fail help you diagnose immediately.
